I would seriously like to better understand the Sigma cameras I own, (SD1M, SD15 and DP2M).

Then ask about specific problems, their causes, possible solutions or workarounds. Ask politely, do not get obsessed with emotional answers, do not try to insult others. Express your opinions in neutral way, do not talk down other people.

Easy? Just generic forum etiquette, nothing more.

I couldn't agree more, Arvo.

Post some photos and point out where you see the problems. And stop labeling people SigMafia and liars.

Well, I tried to offer a helpful suggestion, i.e., that you post some photos. You ignored that and inferred that there's something fundamentally wrong (with me, I'm guessing) and you called my suggestion "sucky". Wow, what am I dealing with here...? I give up. You're not worth the effort - a waste of keystrokes.
